Definitions
- Table or desk tops are often supported by one or more telescopic supports, such that the table or desk top can be raised or lowered to meet the needs of users.
- a common application is an overbed table with vertical adjustability, as found in hospitals and the like.
- this functionality is met by providing inner and outer tubes separated by, preferably, a self-lubricating bearing material such as polytetrafluorethylene. While this arrangement provides adequate utility, in order to provide a telescopic support which extends and retracts smoothly, the components need to be manufactured with relatively high precision, which entails substantial costs.
- a telescopic support forms one aspect for the invention.
- the support comprises an outer leg part and an inner leg part.
- the outer leg part has: a tubular body defining a longitudinal axis and having an interior passage through which the longitudinal axis extends centrally; and one or more longitudinally-extending splines extending radially, inwardly from the tubular body.
- the inner leg part has: a shuttle body part disposed at least in part in the tubular body; and rollers rotatably mounted to the shuttle body part to support the inner leg part for longitudinal reciprocating movement in the tubular body.
- the rollers include, for at least one of said one or more splines, at least one grooved roller having a peripheral groove which receives said spline during said reciprocating movement to constrain said outer and inner leg parts against relative rotation about the longitudinal axis.
- a height-adjustable pedestal-style table forms another aspect of the invention and comprises a foot, a telescopic support and a member.
- the foot defines a base for the table in use.
- the telescopic support comprises: an outer leg part having a tubular body secured to the foot and extending vertically therefrom in use, said tubular body defining a longitudinal axis and having an interior passage through which the longitudinal axis extends centrally; and one or more longitudinally-extending splines extending radially, inwardly from the tubular body.
- the inner leg part has: a shuttle body part disposed at least in part in the tubular body; and rollers rotatably mounted to the shuttle body part to support the inner leg part for longitudinal reciprocating movement in the tubular body.
- the rollers include, for at least one of said one or more splines, at least one grooved roller having a peripheral groove which receives said spline during said reciprocating movement to constrain said outer and inner leg parts against relative rotation about the longitudinal axis.
- the member is secured to the inner leg part and defines a work surface of the table in use.
- a telescopic support forms another aspect of the invention.
- This support comprises an outer leg part and an inner leg part.
- the outer leg part has a tubular body defining a longitudinal axis and having an interior passage through which the longitudinal axis extends centrally.
- the inner leg part has a shuttle body part and rollers.
- the shuttle body part is disposed at least in part in the tubular body.
- the rollers are rotatably mounted to the shuttle body part to support the inner leg part for longitudinal reciprocating movement in the tubular body.
- the fit between the outer leg part and the inner leg part defines a negative allowance and the tubular body deforms elastically during said reciprocating movement to accommodate such negative allowance.
- the invention permits the relatively inexpensive construction of relatively robust desks and tables that can be relatively smoothly raised and lowered.
- FIG. 1 is a perspective, partially cut-away view of a telescopic support constructed according to a preferred embodiment of the invention in use in a height-adjustable, pedestal-style desk which forms another preferred embodiment of the invention;
- FIG. 2 is an enlarged view of encircled area 2 in FIG. 1 ;
- FIG. 3 is an exploded, perspective view of the desk of FIG. 1 , with the desk top removed, for clarity;
- FIG. 4 is a view similar to FIG. 3 , with some parts repositioned;
- FIG. 5 is an enlarged view of encircled area 5 in FIG. 3 ;
- FIG. 6 is an exploded view of the structure of FIG. 5 ;
- FIG. 7 is a view along arrow A of FIG. 4 ;
- FIG. 8 is a cross-sectional view along axis X-X at elevation B of FIG. 1 .
- a height-adjustable pedestal-style table or desk constructed according to a preferred embodiment of the invention and designated with general reference numeral 20 is illustrated in partially-cut away perspective view in FIG. 1 and will be seen to comprise, generally, a foot 22 , a telescopic support 24 and a desk or table top member 26 .
- the telescopic support 24 which will be described initially, is shown in exploded view in FIG. 3 and will be seen to comprise an outer leg part 28 and an inner leg part 30 .
- the outer leg part 28 has an extruded aluminum tubular body 32 which defines a longitudinal axis X-X and has an interior passage 34 through which the longitudinal axis X-X extends centrally.
- the body 32 is generally thin-shelled, but includes a plurality of longitudinally-extending stiffening ribs 36 , 36 ′, best seen in FIG. 8 .
- ribs 36 Six of these ribs 36 are disposed in three pairs 38 , wherein the paired ribs 36 are closely-spaced to one another, the three pairs 38 being equally-spaced around the interior passage 34 .
- the remaining ribs 36 ′ are somewhat larger in cross-section than ribs 36 .
- the outer leg part 28 also has at least one, specifically three, longitudinally-extending splines 40 extending radially, inwardly from the tubular body 32 .
- the splines 40 are formed separately from the tubular body 32 and take the form of steel rods, each snap-fit between the ribs 36 of a respective pair 38 , as shown in FIG. 7 , wherein the ribs 36 of each pair 38 will be seen to define a channel of semi-circular cross-section which receive in tight-fitting relation the respective spline rods 40 .
- the inner leg part 30 has a shuttle body part 42 , rollers 44 , 46 and a fluted body part 50 .
- the shuttle body part 42 is disposed at least in part in the tubular body 32 and, as best seen in FIG. 5 , has a substantially cylindrical center portion 52 and notched plates 54 , 56 secured to the center portion 52 and forming longitudinally-spaced upper and lower ends of the shuffle body part 42 in use.
- the rollers 44 , 46 are steel, are six in number and are arranged in three pairs 48 .
- the rollers 44 , 46 are longitudinally-spaced from one another, each at a respective end of the shuttle body part 42 and fitted in a respective notch 58 defined in the notched plate 54 , 56 defining said end.
- the three pairs 48 are equally spaced around the shuttle body part 42 .
- Each of the rollers 44 , 46 is a grooved roller having a groove 60 in receipt of a respective spline 40 , as shown in FIGS. 1 and 8 , and is mounted to the shuttle body part 42 for rotation by means of an axle 90 having a ball bearing.
- Each axle 90 has an associated socket 92 in which it is received and captured by a pair of washers 94 and bolts 96 , as indicated in FIGS. 5 and 6 .
- the fluted body part 50 is an aluminum extruded member secured by bolts or screws 64 to the upper notched plate 54 of the shuttle body part 42 so as to extend longitudinally therefrom.
- the fluted body part 50 has a plurality of longitudinally-extending external grooves 51 .
- the rollers 44 , 46 roll along the splines 40 , to permit telescopic longitudinal reciprocating movement of the outer leg part 28 and the inner leg part 30 .
- the engagement between the grooves 60 and splines 40 both constrains the outer 28 and inner 30 leg parts against relative rotation about the longitudinal axis X-X and provides for longitudinal alignment of the outer 28 and inner 30 leg parts, to permit constrained reciprocating relative movement parallel to the longitudinal axis X-X.
- the fit between the inner leg part 30 and outer body part 28 is of a negative allowance nature, that is, the interior dimension of the tubular body 32 and splines 40 is smaller than the exterior dimensions of the shuttle body part 42 and rollers 44 , 46 .
- the tubular body 32 elastically deforms to receive the inner leg part 30 .
- This arrangement permits smooth reciprocating motion, notwithstanding minor manufacturing imperfections that may exist. Further assisting this smooth reciprocating motion is a sliding fit between at least one of rollers 44 and its respective axle 90 and at least one of rollers 46 and its respective axle; such rollers 44 , 46 can slide ⁇ 4 mm along their rotational axes to accommodate extrusion imperfections, etc.
- the splines 40 as well as those stiffening ribs 36 ′ that do not form part of the pairs 38 , traverse the external grooves 51 in spaced relation when the fluted body part 50 moves within the tubular body 32 , and similarly traverse notches 58 in upper and lower plates 54 , 54 .
- the accommodation provided by flexure of the tubular body 32 permits the various components to be manufactured relatively inexpensively, i.e. without the need for unduly high precision, with confidence that the product will still reciprocate relatively smoothly in use.
- the structure is also relatively robust.
- the foot 22 forms a base for the table 20
- the telescopic support 24 specifically, the tubular body 32
- the table top member 26 is fitted to the inner leg part 28 to define a substantially horizontal, planar work surface 64 , the elevation of said surface 64 being amenable to adjustment via extension or retraction of the telescopic support 24 associated with said reciprocating movement of the inner 28 and outer 30 leg parts.
- the foot 22 is a substantially wedge-shaped member which defines a socket 66 for receiving the lower end of the telescopic support 24 and has an inclined upper surface 68 that is textured for grip.
- a bottom plate 70 is secured to the lower end of the tubular body 32 by bolts 72 which engage the lower ends of spline rods 40 .
- Bolts 72 are also fitted to the upper ends of spline rods 40 , such that the spline rods 40 are locked as against longitudinal movement relative to the outer body part 32 .
- To the bottom plate 70 is secured, by bolts 74 , a riser bracket 98 .
- bracket 98 is secured by bolts 100 to a drive nut riser 102 .
- Bolts 106 extend through the foot 22 and bottom plate 70 to secure tubular body 32 to foot 22 .
- the table top member 26 is secured to the upper end of the fluted body 50 .
- Such securement in the application shown is provided by an intermediate bracket 76 , which is secured by bolts 78 to the upper end of the fluted body 50 , and to which the table top 26 is secured by screws (not shown).
- An electrical motor 80 is secured by bolts 82 in a recess 84 of the intermediate bracket 76 , and has drivably coupled thereto a threaded driveshaft 86 which, in use, extends into and is threadably received by the drive nut riser 102 , such that rotation of the driveshaft 86 causes extension and retraction of the telescopic support 24 , and cessation of rotation forms a mechanical lock against extension and retraction.
- rollers For example, whereas only three longitudinally-spaced pair of rollers are shown, greater numbers of longitudinally-spaced rollers could be provided. For example, four pairs of longitudinally-spaced rollers could be provided, each pair being spaced 90° from the other.
- the splines could be formed integrally, could take the form of tubes rather than rods, could have cross-sections other than round, and could be secured by welding, adhesive, rivets, screws, etc.
- outer leg part need not be extruded, nor of steel and could be formed, by way of example, by blow or rotationally-molded plastics, or by sonically-welded injection molded components.
- inner leg part need not be hollow, nor fluted, and mechanisms other than threaded shafts could be utilized for vertical adjustment and locking.
